[The TraumaRegister DGU® dataset, its development over 25 years and advances in the care of severely injured patients].

BACKGROUND: Since the publication in 1993, the dataset and documentation form of the TraumaRegister DGU® (TR-DGU) have continuously evolved. On the occasion of the 25th anniversary the authors have analyzed this evolution in order to reflect it in the light of medical progress in the treatment of the severely injured.

MATERIAL AND METHODS: Enrolled in the study were 5 reference data entry sheets from the years 1993, 1996, 2002, 2009 and 2016. Every piece of information (item) queried therein was entered into the study database, was categorized by topic and counted for further analysis.

RESULTS: The arrangement of the 4‑page data entry form has remained practically unchanged since 1993 and includes an average of 212 items. A total of 491 items were identified of which 64 were present throughout every dataset. Based on the average extent of the form this equals a proportion of approximately 30%. The dataset actually shows much more consistency than this number suggests because many changes can be traced back to a smarter design of the data entry form. Most items fell into the categories "results/diagnosis" (143 items/29.1%), "coagulation" (104/21.2%) and "surgical approach" (40/8.1%). Many items serve as raw data for the calculation of prognostic risk scores, such as the trauma and injury severity score (TRISS), the revised injury severity classification II (RISC II) and the trauma associated severe hemorrhage (TASH) score. Currently, nine scores can be calculated from the dataset.

CONCLUSION: The members of the working group TraumaRegister all actively participate in the treatment of severely injured patients. For 25 years this group has managed to unify the latest medical developments and well-established parameters within the TR-DGU dataset at a relatively constant degree of effort for documentation. Practice in place of theory is the driving force behind this development that serves quality assurance and research in the treatment of severely injured patients.
